IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 33,573, dated OctoberQ9, 186i.

To a/ZZ w/bom/ t may con/cern:

Be it known that we, RICHARDSON Con- DINGTON, of Leonidas township, inthe county of St. Joseph, and DoUGAL MGCALL, of the township and countyof Kalamazoo, both in the State of Michigan, have invented new anduseful Improvements in Plows; and we do hereby declare the following tobe afull, clear, and exact description of the same, reference being hadto the accompanying drawings and the letters of reference markedthereon, making a part of this specification, in which- Figure l is aperspective view; Fig. 2, a landside view, and Fig. 3 a reversibleshare.

The letters of reference are: A, beams with handles attached; B,standard-bolt; C C, cutters; D D, mold-boards, EE, shares. F is thelever that moves the fastener. F2 is the fastener; G, frame-work, and HH false landsides.

The beam and handles are made of wood, and swing each time the plow isadjusted to turn a reverse furrow. The frame-work G is in one piece, iscast-iron, and has a right and a left mold-board, cutter, share, andfalse landside attached to it by means of bolts. The lettered parts thatattach to the frame-work G, except the beam A, may be made of eithersteel or iron. The standard-bolt B passes through the beam and throughthe frame-work G, crossing at right angles a line that should extendfrom one point of the plow to the other.

The reversible shares E are alike. A description of either is adescription of the other. Each has two face sides, and each consists ofone piece only. One face side is adapted to the right-hand part and theother to the lefthand part ofthe plow-that is, one face side correspondswith the face of the right-hand moldboard 4and the other to the face ofthe lefthand mold-board; hence when the shares beright-hand portion ofthe plow, and the share that was on the right-h and portion of the plowis turned over and attached to the left-hand portion of the plow. Bythus changing every time the shares become worn, the rounded side isplaced above and the least-worn side below, which will make the shareperform good work until it is too short for use.

- The fastener consists of a notched slide-plate and spring, and theslide is moved by a lever. It is placed in the back end of the beam, itsuse being to secure the same as desired at each adjustment of the plowto turn a reverse furrow. The obj ect of this plow is to turn right andleft furrows alternately, so that no ridges or ldead furrows need bemade.

Ve do not claim, broadly, the combined right and left plow, but

Ve do claim the combination of the parts as follows:

A, beam and handles, B, standard-bolt, C C, cutters; D D, right and leftmold-boards; E E, reversible shares; F, fastener; G, framework, and H Hfalse landsides, when arranged and constructed substantially as and forthe purpose described.
